On March 18, 1925, the Weather Bureau predicted “rains and shifting winds” for Missouri, Illinois, and Indiana. It would be the agency’s greatest blunder.

About 1:00 p.m. near Ellington, Missouri, it produced a tornado so massive, so destructive, and so deadly that it still holds the record for the largest killer twister ever.
